IIRC the search timeout is longer than the accepted timeout, so once you've accepted the search it's possible to get several accepted timeouts from downstream peers before the upstream peer gets a search timeout from you. > The implemented algorithm is that we increase the rate of sending > requests if we complete without timing out ourselves, or receiving a > timeout notification from another node involved in the request (these > are propagated back to source). Cool, I think that matches what I've simulated. > By the way, did you try implementing the throttle with RTT, and > comparing to throttle without? Not yet but I will. Cheers, Michael
